His death comes on the birthday of his close friend Chris Cornell, lead singer of Soundgarden, who passed earlier in 2017 in similar circumstances: suicide. Bennington was found in his southern California home on Thursday, July 20.

Bennington was open about his struggles with mental health from the start, encouraging others to seek help, as seen below.

Bennington, a Phoenix, Arizona native, picked up music at an early age and his career catapulted to success while with Linkin Park. The band released Hybrid Theory, their breakthrough album, in 2000, and the band rose to prominence with singles like "Crawling" and "One Step Closer."

Bennington's music often touched on tough, dark topics like depression, suicide, and death. While dark, Linkin Park and Bennington went on to influence a generation of musicians in rock and nu metal while selling more than 70 million records in the process.

Bands like Evanescence, Of Mice & Men, Bring Me The Horizon, Kevin Rudolf and Emery have cited Linkin Park as a heavy musical influence over the years.

Linkin Park's most recent album, One More Light, was released May 19, with the tour set to kick off July 27.

Bennington leaves behind six children.
